GRAIN-CAR DOOR.

SPECIFICATION forming part of Letters Patent No. 415,468, dated November19, 1889.

Application filed February 16, 1889. Serial No. 390,094. (No model.)

To all whom it may concern.-

Be it known that I, CLIFTON D. PETTIS, of Terre Haute, in the county ofYigo and State of Indiana, have invented a new and Improved GrainarDoor, of which the following is a full, clear, and exact description.

This invention relates to grain-car doors, the object of the inventionbeing to provide an exceedingly simple, cheap, and durable door, and onewhich, when not in use, may be compactly'stowed in the upper portion ofthe car just beneath the carlings.

To the ends named the invention consists of novel constructions,arrangements, and combinat-ions, to be hereinafter more fully described,and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partofthis specification,

in which similar figures of reference indicate corresponding parts inall the views.

Figure 1 is an inner face view of my improved grain-car door, thecarbeing shown in central longitudinal section. Fig. 2 is acrosssectional view taken on line or .r of Fig. 1. Fig. l is a face viewof the wear-plate or hooksocket, which is connected to the outer face ofthe door, near the upper edge thereof. Fig. 1 is an edge view of thesocket shown in Fig. 3. Fig. 5 is a plan view of one of the forgings bymeans of which connect-ion between the door audits supporting hooks orrods is established. Fig. l) is a plan view of one of the toes employedto hold the lower edge of the door close against the door-posts, andFig. 7 is a detail perspective view.

In the drawings, 10 represents a door, to the inner face of which thereare bolted forgings 11, which constitute eyes adapted to receive rods12, formed with open hooks 13 at their lower ends, said rods beingconnected to eyebolts 1;, as shown. At the lower corners and upon theinner face of the door I secure wearplates 15, which, when the door isin the po sition shown in the drawings, bear against toes 16, that arescrewed to the car-floor, the toes serving to hold the lower edge of thedoor against the door-posts, the upper edge of the door being held toplace by hooks 17, which engage eyes 18, carried by the door, the hooksbeing held from displacement by gravity keepers 19, that are pivotallymounted above the hooks and arranged to bear upon the upper edge of saidhooks, as shown in Fig. 2.

In a position proper to receive the upper outer edge of the door I mounta gravity-hook 20, said hook being suspended from one of the carlings,and upon the inner face of the door I secure a wear-plate 21, which isformed with a socket 22, so placed as to be entered by the hook when thedoor is moved, as will be now set forth.

To clear the door 10 when the car is filled with grain, the hooks 17 arethrown from engagement wit-h their eyes 18 and the door is slid upwardfrom the car-floor upon the rods 12, the open hooks 13 permitting therods to pass through the forgings, thus permitting the grain to flowoutward beneath the lower edge of the door, and after sufficient grainhas so flowed outward to permit of the swinging of the door the door isswung upward, so that its lower edge travels, as indicated by the curvedline (1, until said lower edge strikes the eyes 14:. Then the rods 12,and with them the door 10, are moved upward until the hook 20 enters thesocket 22 of the wear-plate 21, the hook being so formed that anaccidental disengagement of the hook is almost impossible.

To facilitate the upward movement of the door, I provide it with ahand-plate secured to the lower outer side of the door, said handplatebeing recessed, as indicated at I) in Fig. 1.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a grain-car door, the combination, with the body ofa car provided with the toes 16 on the floor, of the door 10, providedwith the forgings 11, and the socketed Wear-plate 21 22, secured to theupper inner face of the door, the rods 12, pivoted at their upper endsto the inside of the car-body and having the open hooks 13 on theirlower ends, and the gravity hooks 20, substantially as herein shown anddescribed.
